# NFT Marketplace The HPizza NFT marketplace is a decentralized exchange where users can buy and sell HPizza NFTs. In order to provide the best experience and minimum fees, we have optimized smart contracts specifically for HPizza NFT Farmer in the following ways. 1 - HPizzas can be exchanged directly in the smart contract. Therefore, users do not need to stake their HPizza to be traded on the NFT Marketplace. 2 - This also minimizes gas fees to provide a low-cost experience when trading NFT assets. When a user lists their HPizza for sale, the hPizza hash rate is subtracted from the user's Total Hash Rate. 3 - Therefore, the user does not need to untie, saving on gas fees. When a user purchases an HPizza from the marketplace, the hash rate of the HPizza is added to the user's Total Hash Rate. 4 - Therefore, the user does not need to staking it, saving on gas fees. The Pizza platform charges a 10% exchange fee that goes to the rebuy pool. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
